Firstly, you're actually debating RATM or Less Then Jake. The answer is clearly Rage.
Secondly, Bloc Party could never achieve greatness unless they stopped churning out awful indie tunes.
Thirdly, you drink cider. Are you 12?

yes, im debating seeing LTJ or Rage, because part of me wants to be sweating in a litle tent bouncing round having fun rather than being crushed and finding myself next to some lonatic throwing elbows about, and i like LTJ so there.
Bloc party are great.
Cider is also good, it is better than drinking weak warm piss and constiutes part of your five a day in a warped way.
Im sory you (alex) have seen pennywise before and dont want to see them again, i do.
also the centric thing is used commonly on this site and im sorry to offend you with my poor english.
im gonna have a good time and maybe when you remove your heads frmo out your collective arses you might too.

but for none of the above reasons, except for the cider (nice summer drink), the debate should be jeffrey lewis or rage. Although I probably will use my brain and decide I won't get another chance to see rage.
